Khloe Kardashian has admitted she's still upset with Caitlyn Jenner and how she revealed the news of her transition to the family.

Last April, Caitlyn revealed to the world that she had undergone a gender transition to become a woman during a tell-all interview with Diane Sawyer.

Speaking about Caitlyn’s interview in her most recent episode of Kocktails With Khloe, the reality star said she couldn’t believe she didn’t confide in her family before doing it.

“I didn’t care about the transition. I was actually so happy that she was finally free and didn’t have to carry on this burden," Khloe said on her show. "What I was upset about is that Caitlyn knew she was doing Diane Sawyer before telling us.

Khloe was speaking on her new chat show

"And then told us that she was transitioning but wasn’t really so forthcoming with it so I felt more slighted. Like wow, I had to find out on Diane Sawyer that you’re really transitioning.

"So it is a loss and that’s something that Bruce wasn’t so understanding about."

Speaking on Sirius XM, she told Howard Stern: "They mentioned Bruce had a television show about transitioning, and that's the first we heard of it… We felt betrayed because more business people [knew].

Caitlyn and Khloe also clashed on an episode of KUWTK

"We felt so, like, what the f***! We've been asking you, and why do [business people know]? I never want someone to feel like they have a one-up on our family.

"We've never turned our backs on each [other], with all the cluster f***s of shit in our lives, so why would we now?"

Khloe revealed Caitlyn had talks in private with them after the meeting, but didn't reveal he was going to transition at the time - with the sisters all finding out when they watched his Diane Sawyer interview as a family.
